Several of the middle 20th century parkway projects of master builder Robert Moses also included bike paths. However, when more people could afford to buy motor cars and crowd the streets with them, bicycling declined and the old bikeways fell into disuse and disrepair. Late in the century, bicycling resurged.
Delivery bikes are the most usual vehicle, especially for fast food deliveries over distances of a mile or two (a kilometer or three) in the crowded streets of New York. They are easier to park than motor cars that require spaces along the crowded streets, and no slower in heavy congestion. Most deliverers use old beat-up mountain bikes, with or without additions such as a lock box or a wide carrier rack for pizza. Swift and rugged bicycle messengers use narrower wheels to carry lighter loads that are going a few miles. Specialized cargo bicycles and tricycles carry modestly heavier loads.
Pedicabs became commonplace at the turn of the 21st century. They offer similar advantages to passengers travelling a mile or three, and their novelty attracts tourists including those seeking a guided tour of Central Park. However, on April 23, 2007 the New York City Council voted, over a mayoral veto, to protect the motor taxi industry from unfair competition by limiting their numbers.
On three Saturdays in August 2008, a route on the East Side of Manhattan from Brooklyn Bridge to 72nd Street along Lafayette Street, Park Avenue and other streets was cleared of motor traffic to allow easy non motor use, as an experiment From mid August 2008, two lanes of Broadway between 42nd Street and Herald Square were permanently transformed into a pedestrian plaza with tables, chairs and a bike path.
Some large parks, including Central Park and Prospect Park, ban or restrict motor vehicles during certain weekday hours and all weekend, to promote bicycling. Local bike shops in those neighborhoods usually offer rental bikes. The Bike and Roll company specializes in the rental business, operating in several touristic locations and offering maps and guided tours.
Several organizations, including Five Borough Bicycle Club and Bike New York, conduct escorted tours every weekend. Most are day trips conducted for no fee, while some of the larger or overnight tours require payment. New York Cycle Club and others specialize more in fitness and speed. Bicycle track races run most summer weekends in Kissena Park and elsewhere. Road races are also held, less frequently.
The New York City Department of Transportation distributes a free and annually updated official bike map through bike shops. The map shows each kind of route in a different color, and the locations and names of bike shops and points of touristic interest.
For mixed-mode commuting most suburban commuter rail stations provide free bicycle parking in racks, and some also have bicycle lockers for greater security. Regulations on carrying bicycles on trains vary by railroad and time of day. Bikes are allowed on New York City Subways at all hours, though rush hour crowding makes them difficult to handle. Rules against fastening bikes to subway property, including the fences around street stairs, are enforced more rigorously than those concerning the use of lampposts and other street furniture. Municipal bicycle stands, mostly of the "bike staple" form, are installed for parking in many neighborhoods. A few, including one each at the northwest ends of Pulaski Bridge and Union Square are larger, with a roof.
Transportation Alternatives promotes bicycle commuting and bicycle friendly facilities as part of a larger effort to diminish the impact of cars on urban life.
Approximately a dozen cyclists are killed most years, usually by collision with a moving motor vehicle. Some fatality locations are marked by white-painted "ghost bikes" as a memorial. Traffic accidents also kill approximately 300 pedestrians per year in the city, and a similar number of people inside cars.
